摘要：

Inviscid melt spinning (IMS) was developed nearly two decades ago to spin metal (primarily, stainless steel) fibers from low viscosity melts in a chemically reactive environment (O2, H2S, NH3). This paper evaluates 17 IMS alumina-calcia fibers (50-80% Al2O3) which were melt spun into propane gas. They were X-ray amorphous, had tensile strengths of 21-151 kpsi, diameters of 141-450 μm, and melt and crystallization temperatures ranging from 1341 to 1842°C and from 969 to 1021°C, respectively. The chemical reaction produced a carbonaceous fiber skin or sheath with a thickness of up to 6000 Å. © 1990.
